By controlling algae, cyanobacteria and fouling LG Sonic can efficiently reduce taste and odor problems in a treatment plant. The performance of a drinking water treatment plant is consistent with the amount ol contamination in the water. Growth of algae and other fouling in and before a treatment plant can cause various problems within the process. In general, these issues are related with taste or odor of the water. Growth of algae, cyanobacteria and bacteria within the basins of the plant itself, increase the demand of chemicals or filtration and in turn creating problems with THM (trihalomethane) formation. Other common issues are growth of toxin and geosmin producing cyanobacteria (blue-green algae) within the intake reservoir or dam. These molecules give the water an unpleasant `earthy ` taste.

Carus permanganates have been used in private and public drinking water applications for more than 40 years. Municipal drinking water plants use CAIROX® and AQUOX® potassium permanganates, and CARUSOL® liquid permanganate in both ground water (well) and surface water for Pretreatment, Pre-oxidation and Organics Removal. Today, municipal water providers face increased challenges as more stringent regulations are enacted and public awareness regarding water quality becomes heightened.

Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources.
While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple
analytes, but also in part due to the variety of HPLC stationary phases that are available. In particular, several HPLC phases are available that provide great retention and peak shapes for polar analytes, such as herbicides, even under mostly aqueous mobile phase conditions. The combination of these factors may possibly eliminate need for time-consuming sample preparation.

Drinking water plant AZUD DW to provide the required standard of drinking water for the municipal sector. AZUD DW plants are compact, modular, with solid and easy-handling equipment, fully automated operation and cleaning.

Problem: Drinking water plants that use surface water or ground water under the influence of surface water are susceptible to high levels of organic matter in the raw water. Reduction of organic matter through coagulation/sedimentation and filtration is important to lower the potential for disinfection by-product formation (DBP) and limit operational problems. In addition, organics in water consume the polymers used for the coagulation process, which reduces the efficiency of the treatment. Therefore, optimization of the polymer dosing heavily depends on the concentration of organics.

The UniLux in-situ fluorometer can be configured to detect a number of key parameters that are of importance to the Water Supply Industry. Primarily, the detection of Chlorophyll a in stored water systems, such as reservoirs, assists in the planning and informs decisions on water abstraction in relation to natural algae blooms that regularly occur throughout the year. As well as Chlorophyll a, these in-situ fluorometers can detect cyanobacterias, such as Phycocyanin and Phycoerythrin, which are often associated with algae groups of a toxic nature. Knowledge of concentrations of algae within the water can assist in determining the loading into water processing plants.

These in-situ fluorometers are available as single parameter sensors (UniLux), or 3 channel sensors (TriLux).The CTG FastFlow fast repetition rate fluorometer provides information on the physiological state of algae it monitors. As well as providing detailed information on the growth rate of the algae (which can indicate the occurrence of a future algae bloom), it can immediately inform and alarm on toxins that have accidentally or deliberately been introduced into the water systems, as with the FastGuard system. The FastFlow differs from the FastGuard system in that it logs and displays detailed information on the state of the algae monitored for operational requirements.

Culligan Water installs Greyline SLT32 Level Monitors to control tank levels in their bottling plant in Calgary, Alberta. With non-contacting ultrasonic sensors the SLT32`s control fill and discharge valves in five tanks containing spring water, reverse osmosis water and distilled water.

Real Tech offers solutions that can provide substantial benefits to drinking water treatment plants. Continuous online monitoring can ensure water quality standards are met without the need for chemical overdosing while maintaining high confidence in the safety of the treated water. Significant cost savings can be achieved by optimizing coagulant dosage, reduced sludge production and reduced energy requirements.

Fluoride is a naturally occurring mineral in the soil in some areas of the country. It can leach into the drinking water supply. At low levels, it is not considered to be harmful. In fact, many water treatment plants add fluoride to the water because fluoride has been shown to help decrease tooth decay. However, higher levels can be hazardous to our health.

Drinking water is not the only area requiring flow monitoring. The disposal and cleaning of waste water also requires flow meters. Waste water used to be dumped directly into the soil or an open channel. As awareness has increased, most discharges are now treated to assure long term sustainability. Modern water treatment plants are highly complex systems that require the use of flow sensors to monitor flow velocity in open channels for waste water discharge. Likewise facilities for waste water collection and clarification plants need regular data on flow rate. The use of radar non contact flow measurement and ultrasonic doppler flow meters are particularly efficient. HydroVision can complete flow measurements in all of these areas.

Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.

GE Analytical Instruments offers several Sievers TOC Analyzer models designed specifically to simplify monitoring of drinking water treatment plants. Always knowing the TOC levels throughout a water treatment plant, and improving TOC reduction, can help a plant not only control DBPs, but also implement efficient and potentially cost saving treatment processes.

Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor the algae concentrations and possible toxic blue green algae blooms. During almost 4 months the ALGcontrol measured the total chlorophyll and cyano chlorophyll concentrations of the water reservoir. In order to be able to compare these results, second off-line controls were carried out using the ISO 10260 chlorophyll-a quantification (extraction into ethanol, spectrophotometric detection at 665 and 750 nm).
The results of the off-line standard lab method show a good correlation with the measurements of the ALGcontrol. The good correlation can be verified as well at high as at low concentrations of total chlorophyll.

Nitrogen is a nutrient essential to all forms of life as a basic building block of plant and animal protein. Nevertheless, too much of it can be toxic. The processes used for the removal of ammonium ions from drinking waters include ion exchange. PuriTech`s ION-IX system can be broken up into 4 distinctive zones with each zone operating continuously. The resin is initially loaded with the Ammonia ions (and partially calcium and magnesium)in the adsorption zone. As the ION-IX multi-port valve rotates, the resin that has been saturated with Ammonia ions (and some calcium and magnesium ions)moves into a one-bed displacement zone with softened water to ensure hard water does not cause precipitation within the multi port valve.
